- I am designing the simplest QRP transceiver that can be made. Here are many design tips you can use when you want to make your own radio.

Absolutely excellent job, such a nice sounding receiver with so few parts! And your tiny ATMega328 and si5351 board is brilliant too. No tuning, no display, half a watt and the builtin antenna tuner is well thought through. I love it! Will look at your other projects next.
Thank you for writing about my design.
I had planned for the frequency to come out with Morse code in the earphone, but the software has not been written yet.
Extremely awesome small QRPp transceiver. Received audio was extremely clean and pleasant. Congratulations and thanks for sharing this awesome home brew project.....James VA7VB
A GREAT project... very well laid out into a small tin.. antenna tuner as well, thats genius thinking.. very pleasant side tone too.. well done... look forward to seeing more...
I have found that it is extremely satisfying to homebrew a radio and take it out to the field and see it working. I never got that feeling from a store bought radio. I sit listening to Shortwave in the living room and glance over at my homebrew radio and smile with satisfaction.
Kjempeartig og interessant bygg av radio! Simpel men veldig god utviklet. Flott gjort!
Nice work and use of your 3-D printer to make the various parts; you gave me some ideas for sure.
Also, I was very surprised at the sound of the receiver.
You did a great job and thanks for putting it into a video for all to see.

That is a very nice homebrew. QRPers around the world salute you!
240 km whit 0,2 watts. nice job!
When I was a teenager, I used to love to build little projects, but never built anything beyond a crystal receiver. Your example inspires me to want to build a QRP transceiver sometime soon. KK7PQJ
Wonderful. I wonder what radio (s)was carried by the Norwegian Commandos who raided the heavy water plant ( Vemork) at Telemark during World War II?. I grew up watching the movie " The Heros of Telemark" as a boy in Oregon.
Very nicely constructed transceiver. I like the tin enclosure it looks very robust. I always enjoy your outdoor experimenting in such interesting locations. Thank you for your time in creating this video
Thank you for your comments.
I travel far to find the nicest places.
I’m always amazed by the creativity and simplicity of your designs! Well done.
Very impressive. Well designed and constructed. Tx and Rex sound good.
Thank you for sharing your ideas ! Best wishes from New Zealand. ZL3ABX.
Fantastic what you've done works very well on 200Mw great video.
Excellent project
It's an interesting scheme. I like it. Thank you.
Amazing Helge. That is impressive. Well Done. VE6KBI in Western Canada.
awesome schematic and nice audio rx also tx results...73
very nice project, thank you 73!
Congratulations, it worked very good. Thank you
Nice little rig in in small box. That's real QRP. Hei es 72 de PA3BYW
Snyggt jobbat Helge!!! Vilken fantastisk liten och välfungerande transiever. Helt otroligt verkligen. Stort grattis . Hoppas möta dig på banden någon gång. Men kanske behöver jag lära mig cw först. Hälsningar från Dalarna. 73 SA4GWT Carsten
Tack.
Jag kör både AM och DSB.
Och SSB. Så vi kanske kan ha en QSO.
Thanks for sharing, 73 👍👍👍
Enkel er den, flott arbeid. "Dead bug" konstruksjon er også et alternativ her.
Awesome, no tubes . :D
Imponerende utført ! : Kunne tenkt, å kjøpt en kopi av deg hilsen John/LA6REA
Kjempebra! Hilsen fra W6CMY
Igjen en artg liten konstruksjon som fungerte alldeles utmerket på 60 meter. Det var sterke signaler fra deg noe som er imponerende med bare 0,2w sendereffekt. Alltid hyggelig å være han i andre enden når du tester ut dine små radioer. 73 de Asbjørn, LA5MT.
Takk for det fine svaret. Så flott at du bor på et sted med lite støy.
Awesome! Very inspirational. I love the homebrews videos and how they operate. Do you have a video, or hyperlink, about the Arduino type oscillator design?
Thanks for all your great comments on my videos.
I use the SI5351 on many of my designs.
It is absolutely fantastic, and it costs very little.
I have some information about it on my pages:

@@LA6NCA Thank you Helge very much.
Great Work! Any details about that oscillator?
The SI5351 is a very interesting circuit.
There is a lot of information on the internet about it.
Here is the electrical schematic for the one I made.

Hello from Texas, USA. DE KD5INM
Good day mr.Helge. Is it possible to get a transceiver control sketch so that you can experiment on other bands? 73, R1CAU/QRP
Here is a website where I have posted the program.

@@LA6NCA Hello Mr Helge. I have an idea on how to further simplify the circuit. We can get rid of the signal relay to the mixer. SI5351 has 2 VFOs inside. The output of VFO 1 can be directly fed to the mixer, and the output of VFO 2 can be fed to the amplifier transistors. Based on the TX signal, VFO 2 is turned on and the F-600Hz signal is supplied to the amplifier. In RX mode, VFO 2 is disabled.
Your transceiver is beautiful in its simplicity! Can I place your design on various radio engineering sites and my telegraph group, with a link to your site?
@@Alex_R1CAUExcellent suggestion Alex, I agree with you, a beautiful design so minimal, it makes some of my 'simple CW transceivers' look clumsy! 😂

helt utrulig å se hva du får til, er veldig imponert over folk som bygger radio selv. Ikke dårlig.
Thanks to you both for making this video! It is a great project and so well explained. I learnt a lotl 73 G0ACE
very nice done ! 72 de ON4MGY
